European policymakers are trying to keep Greece in the Eurozone, while ECB and central banks are ready to accept losses in further Greek national debt restructuring. While the total Greece's National Debt is around 220-230 billion euros, second restructuring of national debt may be a last chance to keep Greece solvent. One of the options, offered by ECB is a writedown of 30 per cent or about 70 billion euros of total debt.
